Quick Mount Router Sub-base

This is my quick mount handheld router sub-base to keep the tool straight when routing rabbets inside mirror frames, rounding over edges of narrow pieces and routing top edges of drawer sides without the hassel of removing the original base plate. It takes seconds to mount and get to work. Using 1/4” MDF for its rigidity, my sud-base is 13”-wide by 15”-long (what I had on hand) and all edges have been sanded smooth so they won’t catch.

I drilled a 1-5/8” hole in the center to accept the widest router bit I would use with this handheld router. The two holding clips are made from hardwood and were rabbeted on the tablesaw. The clips are screwed only, from under, so they can be replaced if broken or if I change router. When installing the toggle clamp, make sure the distance from its base and the edge of the router baseplate is a bit more than the depth of the rabbet of the holding clips to be able to insert the router (an issue with my prototype). The two clips and the toggle clamp should be positioned in a triangle and make sure the toggle clamp is opposite to the lock lever.

I soon realized that this sub-base is equivalent to a D-handle to mill edges of any carcasses without tipping over.

Thanks for looking.

Hello Serge

Another tip to all the planet Simple and very effective

In my favorite ( ” for the future” ) but I think It will be more difficult for my bosch router because the base is really different

Wait and see

Thanks for sharing
